Some Attributes of the Lord, that He returns Man as He originated Him, and some of what He does with His Servants
Allah the Exalted said,
وَأَنَّ إِلَى رَبِّكَ الْمُنتَهَى
(And that to your Lord is the End.) meaning, the return of everything on the Day of Resurrection. Ibn Abi Hatim recorded that `Amr bin Maymun Al-Awdi said, "Once, Mu`adh bin Jabal stood up among us and said, `O Children of Awd! I am the emissary of Allah's Messenger ﷺ to you; know that the Return is to Allah, either to Paradise or the Fire."' Allah's statement,
وَأَنَّهُ هُوَ أَضْحَكَ وَأَبْكَى
(And that it is He Who makes you laugh, and makes you weep.) means that He created in His creatures the ability to laugh or weep and the causes for each of these opposites,
وَأَنَّهُ هُوَ رَبُّ الشِّعْرَىٰ (and that He is the One who is the Lord of Sirius ...53:49) The word shi` ra with the diacritical symbol kasrah under the letter shin is the name of a star, called Sirius which is behind Jauza'. Some of the Arab tribes worshipped the mighty star, Sirius, because they regarded it as a source of good or bad luck for them. Allah mentions this star in particular in order to refute their false notion and to affirm that He is the Lord and Master of this star as well, although He is the Creator, Master and Lord of all the stars, heavens and the earth.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 49–54
Every event in this world arises from supernatural causes and nobody but God is capable of causing them to occur. Happiness and sorrow, life and death, the pro-creative system, riches and poverty—all these are the feats of a superpower. Ancient man used to consider the stars as the determining factors in life, while in the present age natural law is considered to govern all happenings. But the fact is that there is a Cause over and above these causes and factors and that is God, the Lord of the universe. Then, how is it legitimate for a man to make anything other than Him the centre of his attention?
